Sentence examples for concentrations positive from inspiring English sources
We illustrate a proposed model of control of NO formation whereby at low concentrations of 4-HNE a negative feedback loop maintains a constant level of NO production with an observed inflection at approximately 1 µM, while at higher 4-HNE concentrations positive feedback is observed.
